TE-116312 Replacement Brush Motor, 220V MFC Hi-Vol Air Sampler Systems SKU: TE-116312

TE-116312 Replacement Brush Motor, 220V MFC Hi-Vol Air Sampler Systems

The TE-116312 is a 220-volt brush-style replacement motor designed specifically for mass flow controlled (MFC) high volume air sampling systems. This motor serves as the primary air movement component in ambient air quality monitoring samplers, providing the necessary suction to draw air through particulate collection filters at EPA-specified flow rates.

Technical Operation

In mass flow controlled systems, this motor works in conjunction with a hot wire anemometer-based flow controller that maintains steady flow rates throughout the sampling period. The MFC system automatically adjusts motor speed as filters begin collecting particulate matter, compensating for increasing resistance to maintain consistent volumetric flow. When the mass flow controller senses decreased air flow, it increases voltage to the motor, which increases blower speed to compensate for filter loading.

System Compatibility

This TE-116312 motor is compatible with TE-116312, TE-116111, and TE-116125 high volume air sampler motor assemblies. It is designed for use in complete MFC sampler systems including TSP and PM10 ambient air monitoring configurations. The motor integrates with TE-5005X series motor assemblies for 220-volt MFC applications.

Maintenance Requirements

This brush-style motor requires periodic brush replacement using TE-33378 motor brushes specifically designed for 220-volt MFC, VFC, and PUF motors. Regular brush inspection and replacement ensures consistent motor performance and prevents damage to the motor commutator. Tisch Environmental recommends following established brush replacement schedules based on operating hours and environmental conditions.

Applications

This motor supports EPA-compliant ambient air quality monitoring for particulate matter sampling, including PM10 systems operating under 40 CFR Part 50, Appendix J requirements. TSP samplers using this motor are commonly deployed for lead sampling and capturing larger particulates such as heavy metals. The motor is suitable for continuous ambient air monitoring stations, industrial hygiene studies, and regulatory compliance monitoring applications.

Note: This is the motor component only. For complete motor assembly systems, see TE-5005X complete motor assembly. Compatible replacement brushes are available as TE-33378. For 110-volt applications, use TE-116311 instead.
